Minosharp - good or bad?

I do intend to get some stones and learn to use them (honest!). But they do represent quite an investment of both time and money. So in the meantime I would like to find something I can use TODAY to sharpen my knives which: -

A) Will give me a reasonable cutting edge on my knives

B) Will not damage my knives

C) Is not too expensive

I have noticed that quite a number of people who seem to know what they're talking about recommend the Minosharp Plus 3 as being rather better than 'basic' sharpeners. It is also recommended by Global.

I have a selection of Wusthof, Victorinox and Kasumi knives. Given that I do understand that stones are best - do any of you guys have any experience with the Minosharp? What are your thoughts?
